Science Diction from Science Friday is back! Their latest episode is all about a recent buzzword: "Introvert." 

In 2013, introverts staged their comeback. For decades, they’d been told to get out of their shells and *smile*, while those  showy, gregarious extroverts were held up as the American ideal. But when one author published a kind of introvert’s manifesto, she sparked an introvert pride movement. Since then, the war of the ‘verts has only escalated, with self-identified introverts accusing extroverts of being shallow and incessantly chatty party monsters, and extroverts declaring introverts self-absorbed shut-ins who are just jealous because extroverts are actually happy. (A contention that studies support.)

It all feels like a very 21st Century, internet-era drama. But the history of the dubious and divisive introvert-extrovert binary began 100 years ago, when Carl Jung fell out with Sigmund Freud, and tried to make sense of where they’d gone wrong. In the process, Jung coined a couple of new terms, and unleashed an enduring cultural obsession with cramming ourselves into personality boxes.
